Hi khai,
Neutrophils and lymph cells both belong to the white blood cell
family, but they are not the same. Simply put, neutrophils protect us
from bacterial infections, while lymph cells protect us from viruses
and produce antibodies.
The following illustration shows how all blood cells develop from a
stem cell. The lymph cells (lymphovtes, lymphs), T-lymph and B-lymphs
develop from a lymph precursor cell.
Granuocytes, of which there are three, Erythrocytes, Basophils, and
neutrophils develop from a granulcytic precursor cell. Neutrophils
are also known as segmented neutrophils (segs), and generically called
a WBC (white blood cells)

Here is another illustration showing the different white cells lines,
as they change into mature cells.

Lymphocytes
============
?There are several kinds of lymphocytes (although they all look alike
under the microscope), each with different functions to perform . The
most common types of lymphocytes are
· B lymphocytes ("B cells"). These are responsible for making antibodies.
· T lymphocytes ("T cells"). There are several subsets of these:
o inflammatory T cells that recruit macrophages and neutrophils to the
site of infection or other tissue damage
o cytotoxic T lymphocytes (CTLs) that kill virus-infected and,
perhaps, tumor cells
o helper T cells that enhance the production of antibodies by B cells?
An experienced medical technologist can often preliminarily
distinguish T cells from B cells under the microscope, contrary to the
statement above.
?White blood cells known as lymphocytes arise from by mitosis of stem
cells in the bone marrow. Some lymphocytes migrate to the thymus and
become T cells that circulate in the blood and are associated with the
lymph nodes and spleen. B cells remain in the bone marrow and develop
before moving into the circulatory and lymph systems. B cells produce
antibodies.?
This site illustrates how lymph cells produce antibodies to fight off invaders.

Neutrophils
===========
?The most abundant of the WBCs. This photomicrograph shows a single
neutrophil surrounded by red blood cells.
Neutrophils squeeze through the capillary walls and into infected
tissue where they kill the invaders (e.g., bacteria) and then engulf
the remnants by phagocytosis.
This is a never-ending task, even in healthy people: Our throat, nasal
passages, and colon harbor vast numbers of bacteria. Most of these are
commensals, and do us no harm. But that is because neutrophils keep
them in check.
However,
· heavy doses of radiation
· chemotherapy
· and many other forms of stress
can reduce the numbers of neutrophils so that formerly harmless
bacteria begin to proliferate. The resulting opportunistic infection
can be life-threatening.?

Here is an illustration showing what the various blood cells look like
after they are stained and seen under the microscope.
